背景：失眠是一种流行的健康主诉，通常难以可靠地评估。需要一种简明有效的评估工具来帮助医生对失眠投诉进行临床评估。目的：本文报道了失眠严重程度指数(ISI)作为失眠筛查指标和治疗研究结果的临床验证。对两个失眠症患者样本进行了ISI的心理测量学特性(内部一致性、同时效度、因子结构)的评估。方法：第一项研究对145名在睡眠障碍门诊接受失眠症评估的患者进行了ISI的内部一致性和同时效度的检验。来自ISI的数据与睡眠日记测量的数据进行了比较。在第二项研究中，对78名老年患者的ISI的同时有效性进行了评估，这些患者参加了一项行为和药物治疗失眠的随机对照试验。将随时间变化的ISI得分与睡眠日记和多导睡眠图获得的得分进行比较。结果：研究1的结果表明，ISI具有足够的内部一致性，是一种可靠的自我报告工具，用于评估感知到的睡眠困难。研究2的结果还表明，ISI是一种有效和敏感的测量手段，可以检测治疗后感觉到的睡眠困难的变化。此外，ISI患者版本与临床医生版本和重要他人版本的得分之间存在着密切的趋同。结论：本研究结果表明，ISI是量化感知失眠严重程度的可靠而有效的工具。在失眠治疗研究中，ISI很可能是一种临床上有用的工具，作为一种筛查设备或结果衡量标准。(C)2001 Elsevier Science B.V.保留所有权利。
Background: Insomnia is a prevalent health complaint that is often difficult to evaluate reliably. There is an important need for brief and valid assessment tools to assist practitioners in the clinical evaluation of insomnia complaints.Objective: This paper reports on the clinical validation of the Insomnia Severity Index (ISI) as a brief screening measure of insomnia and as an outcome measure in treatment research. The psychometric properties (internal consistency, concurrent validity, factor structure) of the ISI were evaluated in two samples of insomnia patients.Methods: The first study examined the internal consistency and concurrent validity of the ISI in 145 patients evaluated for insomnia at a sleep disorders clinic. Data from the ISI were compared to those of a sleep diary measure. In the second study, the concurrent validity of the ISI was evaluated in a sample of 78 older patients who participated in a randomized-controlled trial of behavioral and pharmacological therapies for insomnia. Change scores on the ISI over time were compared with those obtained from sleep diaries and polysomnography. Comparisons were also made between ISI scores obtained from patients, significant others, and clinicians.Results: The results of Study 1 showed that the ISI has adequate internal consistency and is a reliable self-report measure to evaluate perceived sleep difficulties. The results from Study 2 also indicated that the ISI is a valid and sensitive measure to detect changes in perceived sleep difficulties with treatment. In addition, there is a close convergence between scores obtained from the ISI patient's version and those from the clinician's and significant other's versions.Conclusions: The present findings indicate that the ISI is a reliable and valid instrument to quantify perceived insomnia severity. The ISI is likely to be a clinically useful tool as a screening device or as an outcome measure in insomnia treatment research. (C) 2001 Elsevier Science B.V. All rights reserved.
